Body foaming, to reduce number and the time that the high-pressure foam needed for the electric heater 10 operates, improve manufacture efficiency.
In the present embodiment, spacing flange 111, and the spacing flange are provided with the openend that housing 11 is connected with end cap 17
Stopper slot 112 between 111 and housing 11 formed with opening towards another openend.Wherein, the stopper slot 112 is preferably in ring
Shape, and along the circumferentially disposed of housing 11, the stopper slot 112 can also be set in interruption, be not especially limited herein.End cap
17 include lid body 171 and from the periphery of lid body 171 to the installation flange 101 extended away from the direction of inner bag 12.Should
Installation flange 101 is embedded and is installed on stopper slot 112, in this way, when end cap 17 is when by high-pressure foam pressure outwardly, this is spacing
Flange 111 can be formed to the installation flange 101 being embedded in stopper slot 112 to be stopped, inner bag is faced away from so as to limit end cap 17
12 direction departs from housing 11.In addition, under high-pressure foam pressure, the free end of installation flange 101 can closely abut stopper slot
112 bottom land so that between end cap 17 and housing 11 formed be tightly connected, so as to avoid the expanded material of high pressure from end cap 17 with
Overflow junction between housing 11.
Reference picture 5 and Fig. 6, the end cap 17 also include connection cover body 171 with installing the connection flange 102 of flange 101, should
Connect flange 102 to towards the direction of inner bag 12 to extend, and opened between the connection flange 102 and installation flange 101 formed with one
Mouth deviates from the escape groove 103 of inner bag 12.Wherein, the escape groove 103 is preferably that ring-type is set, and along the circumferentially disposed of end cap 17,
The escape groove 103 can also be set in interruption, be not especially limited herein.In the present embodiment, it is embedded in installation flange 101
While being installed on stopper slot 112, spacing flange 111, which is also embedded, to be installed in the escape groove 103, and causes lid body 171
Outer surface is all along being connected with the corresponding opening end end face of housing 11, in this way, the corresponding opening end end face of housing 11 can be avoided to cover
The outer surface edge of body 171 forms protrusion, it will be understood that is protruded if being formed, dust etc. is easy to be deposited on, and is not easy to electricity
The cleaning of water heater 10.In addition, in the present embodiment, the opening of the escape groove 103 is preferably being on the direction of inner bag 12
Open up and put, in order to which spacing flange 111 is embedded in the escape groove 103.
It should be noted that inner bag 12 has on the length bearing of trend of housing 11 in the first end that is oppositely arranged and the
Two ends, the second end offer courage mouth；Above-mentioned end cap 17 includes the first end cap 13 and the second end cap 14, wherein, the first end cap 13 covers
Set located at an openend of housing 11, and close to the first end of inner bag 12；Second end cap 14 is located at another opening of housing 11
End, and 14 corresponding courage mouth of the second end cap offers operation aperture 141, and removably it is covered with second in the operation aperture 141
Lid 16 is installed.In the present embodiment, the setting of the second end cap 14 and the second installation lid 16 can avoid the pipeline at the courage mouth of inner bag 12
Structure is exposed outside.In addition, the detachable setting of the second installation lid 16, can be easy to the maintenance and replacing of the pipeline structure.The
The outer surface of one end cap 13 is also preferably equipped with the first installation lid 15, and it is in symmetrical status that the first installation lid 15 and second, which installs lid 16,
In the both ends of housing 11, i other words, the first installation lid 15 is identically shaped and sized with the second installation lid 16, in this way, can
So that the left and right ends of the electric heater 10 have basically identical surface structure.In addition, first installation lid 15 may also function as into
One step strengthens the effect of the intensity of the first end cap 13.
The technical solution of the utility model by a flange 111 of being limited in the corresponding opening end of housing 11, when end cap by
When arriving high-pressure foam pressure outwardly, the spacing flange 111 can form resistance to the installation flange 101 being embedded in stopper slot 112
Gear, depart from housing 11 towards the direction away from inner bag 12 so as to limit end cap；In addition, under high-pressure foam pressure, flange 101 is installed
Free end can closely abut the bottom land of stopper slot 112, be tightly connected so as to be formed between end cap and housing 11, so as to avoid height
Overflow junction of the expanded material of pressure between end cap and housing 11.
Further, reference picture 7 and Fig. 8, further, first end cap 13 also include oneself of connection installation flange 101
By the sealing flange 131 held, the sealing flange 131 extends to towards the direction of inner bag 12, and the outer surface of the sealing flange 131
Setting is bonded with the inner surface of housing 11, in this way, by way of being bonded face face, can extend and lead to needed for high-pressure foam material spilling
The distance crossed, so as to further improve the sealing connected between the first end cap 13 and housing 11.
In addition, in the present embodiment, installation flange 101 is with sealing the junction of flange 131 preferably away from the side of inner bag 12
It is in tapered setting upwards, in order to embedded stopper slot 112.
In the present embodiment, further to improve the sealing connected between the first end cap 13 and housing 11, flange is sealed
131 is preferably be bonded with housing 11 by sticky glue, because the deformation of not phase is and caused by, to seal flange by the filling of sticky glue
Gap between 131 outer surfaces and the inner surface of housing 11.Especially, still there is certain elastic sticky glue after solidification can be used.
Right the design not limited to this, in other embodiment, also elastic seal ring can be set between sealing flange 131 and housing 11
(not shown), by the adaptive elasticity of elastic seal ring, to eliminate between the sealing outer surface of flange 131 and the inner surface of housing 11
Deformation gap.
In the utility model, when being provided with the elastic seal ring between sealing flange 131 and housing 11, sealing is turned over
The outer surface on side 131 is preferably provided with the locating slot (not shown) being arranged for elastic seal ring, to avoid the elastic seal ring from pacifying
The displacement for departing from sealing flange 131 is produced during dress, improves the convenience assembled between the first end cap 13 and housing 11；When
So, the elastic seal ring part is revealed in locating slot, and the inner surface of housing 11 is contradicted with elasticity, so as to lift-off seal effect.Its
In, the locating slot preferably in a ring, and along the circumferentially disposed of the first end cap 13, to strengthen its sealing effectiveness.In some other realities
Apply in example, the locating slot can also be set in interruption, be not especially limited herein
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model,
Every equivalent structure change under inventive concept of the present utility model, made using the utility model specification and accompanying drawing content
Change, or directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
